I think I've found it!! A way to wear Shelby out for at least a few minutes!
We went for our 2 mile walk today in the middle of the day rather than at one of the more cooler ends of it. Upon arriving home Shelby flopped down on the floor and is refusing to move. She munches on the ice cubes I bring her, and is panting and looking happy and (most importantly) TIRED!!!!!!!
I'll have to remember this! Its sunny, and only 65F out, but it seemed to be warm enough to wear her out! I will need to remember this for the summer and take her in the mornings or evenings when it is cooler so she doesn't suffer from heat stroke.
Of course, I walk 2 miles, but with her retractable leash and following her nose back and forth, she probably logs more than 3 miles!
